NAME

       enter_quiet_zone, exit_quiet_zone - Prevent keyboard interruption of program actions (Enhanced Security)

LIBRARY

       Security Library - libsecurity.so

SYNOPSIS

       #include <prot.h>
       void enter_quiet_zone();

       #include <prot.h>
       void exit_quiet_zone();

DESCRIPTION

       The  function  sets  the appropriate signals to a state that prevents keyboard interruption of program actions.	If this function is called
       multiple times without an intervening call, nothing is done.  If an alarm has been set, the time left to go is saved.

       The function restores the signals to their previous state.  Do not call this function from reentrant code because it uses a static area.  A
       pending alarm clock is restored.

       The signals that are affected are SIGHUP, SIGINT, SIGQUIT, SIGSYS, SIGALRM.

NAME

       sia_chdir - Interface to the chdir system call - SIA (Security Integration Architecture)

LIBRARY

       Standard C library (libc.so and libc.a)

SYNOPSIS

       #include <siad.h>

       int sia_chdir(
	    const char *  directory,
	    time_t	  timelimit);

PARAMETERS

       directory      The specified new working directory.  The parameter must be an ASCII string.  If it is a NULL, SIAFAIL is returned.

       timelimit      The  number of seconds to allow for the chdir call.  If a 0 is specified, there is no timeout.  If the value is less than 0,
		      SIA_DEF_TIMEOUT is used.

DESCRIPTION

       The sia_chdir() routine implements a "NFS-safe" way to change the current working directory.  This routine calls the  chdir()  system  call
       which  is  protected  by  alarm()  and  signal-handling for SIGALRM, SIGHUP, SIGINT, SIGQUIT, and SIGTERM.  Receipt of any of these signals
       causes the chdir() operation to fail.  If the chdir call completes within the time limit given, the call succeeds.

RETURN VALUES

       The sia_chdir() routine returns SIASUCCESS or SIAFAIL.

ERRORS

       The errno value is not (normally) set explicitly by sia_* routines.  The errno values are those returned from the dynamic loader interface,
       from  dependent	(siad_*)  routines,  or  from malloc.  Possible errors include resource constraints (no memory) and various authentication
       failures.
